Specification of Letters Patent.

Patented Dec. 11, 1917.

Application filed Kay 20, 1916, Serial No. 98,884. Renewed October 4, 1917. Serial No. 194,807.

To all whom it may concern:

Be it known that we, HERSGHEL M. CoN- NOR and DON D. MILES, both, citizens of the United States, both residing at San F rancisco, in the county of San Francisco and State of California,-have invented certain new and useful Improvements in Fllm Printing and Projecting Apparatus; and

a we do hereby declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates-to a film printing and projecting apparatus adapted for. amateur and professional use, and has for one of its objects to provide a machine of this character which will be comparatively simple in construction, certain in action, and more efficient in use than those heretofore proposed. Y

With these and other objects in wow the invention consists in the novel details of construction and combination of parts, more fully hereinafter disclosed and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of this'specification in which like numerals designate like parts in all the vieWs Figure 1 is a diagrammatic side elevational view of a projecting and, printing machine made in accordance with this in-- vention;

Fig. 2 is anenlarged side elevational view of a portion of the parts shown in Fig. 1 illustrating the interior construction of the machine when used for projecting purposes;

Fig. 3 is an enlarged side elevational view of a portion of the parts shown in Fig. 2 with certain additional parts added illustrating the use of the machine for printing purposes; and, Fig. 4 is a longitudinal sectional view particularly illustrating the film reversing mechanism.

1 indicates any suitable support, in this instance shown as a tripod head to which is attached the supporting bracket or member 2, provided with the upwardly extending member 3, and with the downwardly extending members 4 and 5. To the upwardly extending member 3 is pivoted as at 6 the film carrying reel 7, and to the downwardly extending member 5 is pivoted as at 8 the film carrying reel 9. The part 3 .p'ref erably makes substantially a right angle with the part 2 in order to accommodate the casing 10 which is preferably made rectangularas shown, and said casing is provided with the crank ll and power shaft 12, to which is rigidly attached the pulley 13, around which the belt 14 passes, and on I the pivot 8 is also secured the pulley 15 which likewise accommodates said belt 14. The film is represented at 16, it passes over the guides 17 and 18 into the reel 7, and passes out of said reel over the guide 19 through the casing 10, and over the guide 20 into the reel 9, all as will be clear from the drawings.

21 re resents a projecting lens attached to the casing 10 and 22 represents any suitshown. After leaving said sprocket 26 the said developed film passes over the guides 28 and 29 to form the loop 30 down past the aperture tube 31 where it is engaged by the feeding pin 32, and is formedinto the loop 33, whence it passes over the guide 34: into engagement with the feeding sprocket 35, and out of the opening 36, with which the casing 10 is also provided, and from said opening 36 said developed film 16 passes into the winding reel 9 all as will be clear from Figs. 1 and 2.

The front of the casing 10 is provided with the projecting lens diagrammatically indicated at 21 and at its back, said casing is provided with an enlarged opening 38 adapted to receive the light tight connection 23 between said casing 10 and the lamp house 22, which may be of any suitable construction, and provided with any suitable source of light 39, but preferably in the form of an incandescent lamp, -especially made for pro ecting purposes. 40 indicates any suitable condenser which may be removably secured to the interior of the easing 10 or otherwise associated with the lamp house 22.

The optical axis of the condenser 40 coincides with the optical axis of the projecting lens 21 and of the aperture tube 31. The feeding sprockets 26 and 35 being suitably rotated by connections not shown, with the crank 11, and the film feeding pins 32 being reciprocated up and down by connections also not shown, from said crank 11, it is evident that the film 16 will be pulled out of the reel 7 and carried past the aperture tube 31, and also rolled up on the reel 9,

whereupon light coming from the lamp 39 through the condenser 420 will project the developed pictures on said film 16 through the lens 21 onto any screen or other refiect ing object which may be provided.

It often happens that it is convenient or desirable to print pictures from a developed film carrying negatives on an undeveloped film, and this machine may be usedfor this purpose when the parts are arranged as are indicated in Fig. 3. That is to say, in such cases the film 16 above described is fed through the machine in the same manner as has been already disclosed and simultaneously with the feeding of said film 16 through the machine, there is fed through the machine the undeveloped film 50 in close contact with .said film 16. In other 2. words, as is fully illustrated and disclosed in our copending application Serial No. 98883 filed May 20,1916, and entitled Moving picture machines, we have described an apparatus comprising a pair of film reels or holders here lettered 51 and 52, the reel 51 being adapted to feed out an undeveloped film and the reel 52 being adapted to take up the undeveloped film and we have fur-' ther disclosed how said undeveloped film may be passed around a sprocket such as 26, past an aperture tube such as 31, and around a sprocket such as 35, and be rolled up on a-take up reel such as 52. In the present case the mechanism is the same or substantially the same, and as is indicated in Figs. 3 and 4, this said undevelopedv film is in close contact with the developed film 16 illustrated in dotted lines in said Figs.

2 3 and 4;" andin full lines in Fig. 2.

That is to say, I power being applied to the shaft 200 by any suitable means as for example that shown in our said copending application, the pulley 201 is rotated, which in turn rotates the spring belt 202 and this said belt rotates the pulley 203 constituting a portion of any suitable reversing clutch 65, such for example as that illustrated in our said copending application 98883. This said clutch is provided with the tubular 'members 205 and 206 which are rotated in predetermined directions according to the direction which the shaft 200 is rotated, and

control at will the rotations of the tubes 55 and 560, and thereby the reels 52 and 51, andthe two films 16 and 50 being thus fed continuously through the machine together, the developed negatives on the film 16 come opposite the aperture tube 31.

' In printing from the film 16 onto the film 50, the lens 21 is removed, and light from any suitable source, not shown, is projected through the opening thus produced, through the shutter 53 and aperture tube 31, whereupon latent images are formed upon the film 50 and said exposed film being wound upon the reel 52, it may be developed in any usualor desired manner.

In the printing of pictures in the manner just disclosed it is an important feature of this invention that we are enabled to use the open ended tube 55, in order to ascertain whether the light is proper and therefore whether or not the developed positives will be correct as to sharpness of definition. In the use of this tube 55 for'pri-nting we propose to place therein, at any desired position, a ruby glass 56, so that the images on the negative carried by the film 16 may be viewed through the back of the undeveloped film 50, so that the operator may ascertain from the appearance of these images whether or not the light is right for producing sharply defined positives from said negatives. This ruby glass may be placed in any convenient position in the tube 55, and performs two important functions. In the first place it prevents actinic rays from'striking the back of the undeveloped film 50, and thus fogging the film, andin the second place, it provides a uniform color to the images from the film 16, so that the operator has something with which he may compare the observed images and thus make up his mind whether or not they have the right appearance to produce the right results.

the undeveloped film 50 may be had.

66 represents the sliding rod for removing the closure 67 from in front of the aperture tube 31 also disclosed in our said application above and 68 represents the hinge of the late 69 from its full line 7 plate 69 which normally closes the rear end of the said aperture tube31.

When pro ecting pictures through this machine it is necessary to swing the said osition shown in ig. 3 upwardly or out of t e way as is indicated in Fig. 2, for by this means the aperture through the tube 31 is greatly enlarged for projecting purposes On the other hand, when printing, as indicated in Fig. 3, a smaller aperture is desired and then the cover plate 67 is pulled or pushed out of the way by means of the rod 66 whereu on a smaller aperture through the plate 69 1s hadand of the proper size for printing pictures, all as will be further understood from our said co-pending application above.

70 represents an intermittently operating film feeding lever which is provided with an enlarged ortion to accommodate a slot in which reclprocates a roller pin carried by a cam, as illustrated; and the cam being rotated by any suitable mechanism, not shown, said lever together with its reduced free end or driving pin 32 is moved up and down on its pivot shown at the left on Fig. 2, whereupon said pin projecting through the usual perforations carried by the film 60, moves said film downwardly as seen in Fig. 2. On the other hand, after said cam and pivot pin have moved in a clockwise direction from 'the position shown in Fig. 2 through an angle of 180 degrees, a continued motion of said cam and roller pivot will move said lever 70 in the direction of its length or toward the left as seen in Fig. 2, whereupon the driving pin 32 will be withdrawn from the perforations in the film, and again brought to the position shown in Fig. 2, all as is more fully disclosed in our copending application, Sr. No. 98883 filed May 20, 1916, and entitled Intermittent feeding mechanisms. An important feature of this invention resides in the fact that the outer casing 10 is chosen of such dimensions that it can accommodate a condensing apparatus 40 which may be secured in the aperture 38, as well as the take up and pay out reels 51 and 52. In other words, the condensing apparatus is readily removable to convert the instrument into a printing device, or the reels are readily removable to convert the instrument into a camera, all as will be clear from Figs. 2 and 4.

75 represents ways carried by the inside of the casing 10, fitting in slots 76, c rried bythe framework 77 of the machine p f'oper, and the moving parts of this machine, as well as the film holding reels 51 and 52 may be readily slid in and slid out of said casing 10, on said ways and grooves. It thus results that it is a comparatively easy matter to remove the mechanism from the casing for the purpose of repairs, for cleaning, or for adjustment, or for any other purpose desired.

The enlarged ca 61 fits and closes the opening 38 when t e connection 23 to the lamp house 22 is not employed, as will be clear from Fi 3.

The operatlon of this machine will be readilyunderstood from the foregoing, but may be br efly summarized as follows: When it 1s desired to use themachine as a projector, the parts being in the position shown in Fig. 1, the turning of the crank 11 will unwind. the film from the reel 7 pull it down through the opening 25, on the casing 10, cause the said film to pass the aperture tube 31, and out of the opening 36 on said casing, and to be wound up on the reel 9 by means of the belt 14. 7

Later, when all of the film has been unwound from the reel 7 and it is desired to rewind the same on said reel, the said film 1 6 may be led utiralong the dotted line position, shown in ig. 1, threaded into said reel 7, where upon the belt 14 may be removed from its full line position shown in Fig. 1, and placed in its dotted line position shown in said figure, whereupon a proper turning of the crank 11 will now unwind the film from the reel 9 and Wind it up again on the reel 7, ready for another projection. When employing this machine as a proectmg apparatus, it is necessary to remove from the casing 10 the film reels 51 and 52, as well as the clutch mechanism, 65, so that the machine may accommodate the condenser 40, and it is further necessary to connect the lamp house 22 by a light tight connection, such as 23 with the said casing 10, and it' is further necessary to move the aperture closing gate 69 out of the way of the aperture tube 31, as is indicated in Fig. 2. The lens 21 remains in position as shown in the drawings.

On the-other hand, when it is desired to employ this machine as a printing device, the reels 51 and 52, as well as the clutch reversing mechanism 65 and its associated parts, are placed in position inside the casing 10, as illustrated in Fig. 3, whereupon the mechanism is so arranged as is disclosed in our said copending application, Serial No. 98883, above mentioned, that the undeveloped film 50 is readily fed out of one reel 51 and readily taken up on the other reel 52 or vice versa. In the meantime a developed film, such as 16, carrying negative pictures of the object to be printed, is fed down simultaneously and in close contact with the undeveloped film 50 and the lens 21, being removed, and the aperture closing plate 69 being closed down in the position shown in Fig. 3, while the sliding plate 67 is removed to produce a smaller aperture, then light from any suitable source not shown, may be allowed to enter through the aperture tube 31, and to strike the developed film 16, and roduce latent images onthe undeveloped dlm 50. In the meantime the operator by removing the smaller cap 60 with which the larger cap 61 is provided may view the back of the undeveloped film through the tube 55 and ruby glass 56 and thus judge from the appearance of the images appearing on said film 50 whether ornot the light is just right for producing the y best effects.

It should be mentioned that 53 represents a suitable shutter driven by the gears 81, 82 and carried by the sleeve 83.

It is an important feature of this invention that by the mechanism disclosed, the operator is enabled to print his pictures in full daylight. That is to say, the undeveloped film 50 is kept at all times in a light tight box, while the developed film 16 being 20 already developed can be freely exposed to the light. Not only is the undeveloped film 50 exposed in a light tight box, but it is wound up on a reel such as 52 where itmay be reserved in position free from all light and may be earned to any convenientplace at any convenient time after exposure and there developed.

- The entire mechanism as will be seen from the drawings is exceedingly compact and may be readily carried about by amateurs or professionals much after the manner that kodaks are at present transported. Further the mechanism as above disclosed may be readily slipped in and slipped out of the casing on the ways 75 for the purpose of cleanlng or repair, and also in order to facilitate the threading of the films .through the mechanism.

The belt 14 is preferably made of a yielding or stretchable material such as rubber or a helically coiled steel spring, so that as the diameter of the coiled film increases said belt will slip while still maintaining the necessaryfriction to drive said reel.

5 It is-obvious that those skilled in the art may vary the details of construction, as well as the arrangement of parts, without departing'from the spirit of the invention, and therefore we do not wish to be limited 5. to the above disclosure except as may be required by the claims.
